About Telestax

Telestax provides communications platform software for service providers. It maintains the open-source Restcomm project and sells a hosted version, Restcomm Cloud, so operators can offer programmable voice and messaging to their own customers.

  • Advanced IVR and chatbots — building blocks for omnichannel applications.
  • Operator options — support for customers using their own carriers, and white labelling.
